Application filed January 10, 1910. Serial No. 537,170.

To all whom it may concern Be it known that I, Gnonon H. SMITH,

citizen of the United States, and resident of l i l Nutley, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in 'lypelvriting Mal chines, of which the following is a. specifica 1 tion. p i My invention relates to ribbon mechanism t for typewriting machines and the general object of said invention is to )rovide 1mproved (it .ices of the class specified. More specifically one of the ob ects of my invention is to provide simple and efficient i means for enabling a ribbon to be used substantially throughout its width and particularly in a visible writing machine where the ribbon is vibrated toward and away from f the printing point at printing operation. Another object is to provide means fort dispensing with the means for cross feeding the ribbon or varying itsthrow automatically and to provide hand controlled means for setting the ribbon in one or another of a plurality of predetermined positions so as to enable predetermined widthwise portions of the ribbon to be made use of. 1 Other specific objects will hereinafter appear. i To the above ends my invention consists t in the features of devices and after described in the claims. t In the accompanying drawings which illustrate one form of my invention, Figure l 1 is a fragmentary vertical central view 1 taken fore and aft of a typcwriting machine embodying my invention, only so much of;

of construction. combinations arrangements of parts hereinand particularly pointed out the machine as is necessary to a clear understanding of my invention being disclosed. Fig. 2 is a front elevation of the machine, parts bein in section, and other parts being omitte and broken away. Fig. 3 is a skeleton view showing various parts of the ribbon mechanism in side elevation, said part-S being shown in different. relationship from that in which they appear in Fig. 1. Fig. 4 is a fragmentary side view partly in section showing stop devices hereinafter more specifically referred to. Fig. 5 is a perspective view of a ribbon carrier sup porting device or frame and the element on which the same is mounted. Fig. 6 is a fragi mentary front view of a locking element or plate cooperati e with a ribbon controlling hey, the support of said element also being shown. Fig. 7 is a diagrammatic lan view of the mechanism for feeding tie ribbon longitudinally. Fig. 8 is an enlarged fragmentary front view showing parts of the ribbon vibrating mechanism and devices for controlling the same, said parts and devices appearing in different relationship from that shown in Fig. 2. Fig. 9 is a. vertical sectional view of certain of the devices shown in Fig. 8. Figs. 10 and 11 are fragmentary face views of ribbons, said views illustrating paths which may be followed by the types along the ribbons at different times.

Referring first to Figs. 1 and 2. the main frame of the machine is shown as comprising a base 1. corner posts 2 A platen 4 is mounted in i, said carriage being connected by a band or strap 5 with a power device or spring drum 6 pivoted on the frame of the machine. The step-by-step movements of the carriugtiare controlled by suitable feeding devices (not shown). Type bars (not shown) are adapted to cooperate with the. front face of the platen, said typo bars being actuated by key levers 7 fulcrumed at 8 in the rear of the base, each key lever being provided with a. restoring spring 9 which normally maintains the lever in contact with a cushion 10 as shown in Fig. 1. A ribbon 11 is wound on ribbon spools 12', the ribbon spools being vertically disposed one at each and a top plate 3. a suitable carriage side of the machine and below the top plate.

The ribbon spools are mounted each on a horizontal rearwardlyextending shaft 13, said shaft bearing in lugs 13 depending from the top plate 3 and as shown in Figs. 1, 2 and 7 carrying at its rear a beveled pinion 14 which is adapted to mesh with a beveled pinion 15, the two pinions 15 being mounted at the ends of a power or ribbon driving shaft 16 which is rotatively and slidably supported in brackets or lugs 16 depending from the top plate. Said power or driving shaft is adapted to receive rotary motion from the spring drum 6 during stepby-step feeding movements of the carriage through connections which include beveled pinions 17 and 18. The pinion 17 is connected with the spring drum and the pinion 18 which constantly meshes with the pinion 17 has a pin and slot conne tion with the t platen to receive the impact of the types at driving shaft 16 which permits endwisc movement of the shaft relativelyto the pin ion but compels said shaft to participate in K rotary movements of said pinion.

be understood that the driving shaft to movable endwise to and fro so as to etiect alternate engagement between the beveled thence turns horizontally inward. beings guided by curved guides 19. Midway be,- tween the guides 19 the ribbon is threaded through slots 20 formed in the head or upper portion of a vibratory ribbon vibrator 21, the vibrator being cut away between the slots as indicated at to provide an opcir ing through which the types may cooperate witlnthe paper and platen through the ribbon. The vibrator has a downward exten sion or stem 23 which is bent or twisted at right. angles to the body of the vibrator and so that said tem is in a fore and a ti plane. Ears 2 are bent forward from the lower portion of the body 21 of the vibrator. said ears receiving pivotal connections 25 which pivotally support the vibrator on a supporting or lever member which is best. shown in Figs. 2 and 5. Said supporting member or frame comprises a pair of parallel horizontal arms 26, said arms curving upward at their forward ends and receiving the pivots 25 and extend ng upward at their rear ends to receive'pivot screws 27 by which the sup porting member or lever frame pivotally attached to a block 2S,'said block being secured by screws 29 to the top plate 3. The

arms 26 are'connected at the rear by a crossor roller 32 rotatable on a screw pin 32 As hereinafter described the roller 32 is adapted to cooperate with devices for automatically varying the position of the supporting member and the vibrator which it carries, thus providing for the cross feed of the ribbon. As will be best understood from Fig. 1, the vibrator normally maintains the printing portion of the ribbon, or that portion which crosses the opening 22, in front of and opposite the printing point a on the front face of the platen but separated from and forward of said printing point so that normally the printing point isvisible to the operator.' Means are provided for swinging the vibrator substantially radially of the platen as distinguished from a movement tangential of the platen, and backward toward the platen so as to bring the ribbon in close proximity to the printing face of the printing perations. The swinging or vibrating means for the ribbon are under the control o' the printing keys so that each printing key is capable of effecting a vibration of the vibrator and ribbon from normal p wit ion backward toward the platen and then forward away from the platen. The vibrating means comprises alink 33 pivoted at 34 to the stem 23 and extending horizontally rearward. said link being connected at its rear end at 33 to the upwardly extending arm 36 of a bell crank lever which further comprises a forwardly extending arm 37. The bell crank lever provided with a hub 38 which is secured by a set. screw 3!) to a rock shaft to. 2lltl rock haft as ll0\\'l1 in Figs. 1 and 2 extending from side to side of the machine and bearing in standards -l-1 rising from the side plates I of the base 1. The arm 3? of the bell crank carries a depe nling link 42. said link being connected to a universal bar 2 which extends from side to side of the machine beneath the key levers T and is adapted to be actuated by each of said key levers. The universal bar is supported at its ends by links l-t which depend from arms 45 secured to and extending horizontally rearward from a rock shaft 4.6 which bears ill screw pivots 47 secured in the side plates 1 of the base. The rock shaft 46 also carries a rearwardly extending arm 48 which is connected to and adapted to operate the car riage feeding or escapement devices (not shown). i hen any printing key is operated it will depress the universal bar 43, pulling down the link 42, swinging the bell crank 36, 37 on its pivot and moving the link 33 forward, said link swinging the stem 23 of the vibrator forward about the pivots 25 and swinging the upper part or body of said vibrator rearward so as to move the printing portion of the ribbon close to the platen in advance of the actuated type bar to receive the impact thereof. The restoring spring 9 of the actuated key lever will operate to return the said key lever to normal position: and a coiled spring 40 on the rock shaft 40 may be provided to restore the train of vibrating devices and the vibrator to normal position. The vibratory movements of the ribbon carrier or vibrator are independent of its supporting frame. If the pivotal center 25 around which the vibrator is turned at printing operation is moved up or down toward and away from the printing point, the bodily normal position of the vibrator will be varied and the widthwise portion of the ribbon presented to the type by the following vibratory movements will be altered. Means are provided for moving the pivotal center 25 progressively up and down by tau tomatic means so that the ribbon may be used progressively crosswise of its width. The automatic rho-ans in the present instance comprise a double arc-shaped cam 49 which is adapted to engage with the roller 32 and to be turned so as to move said roller forward and rearward. thus causing the supporting member to swing on its fixed pivotal enter 27. the parallel arms 26 of said member swinging up and down and bodil v raising and lowering the ribbon vibrator. As best shown in Figs. 2 and 5), the device or cam 49 is integral with a hub portion 50. said hub portion being formed with a (ircumferential depression or groove 51. The cam member comprising the hub 50 and cam 49 bears loosely on a tubular sleeve 52 which is driven through an arm or lug 53 depending from the underside ot the top plate so that said tubular bearing is rigid on said arm. The ribbon winding shaft 1b passes through the tubular bearing the bore f said bearing being greater than the diameter sleeve does not touch the shait. member ll). 30 in adapted to receive rotarv through devices said pin being screwed into the rain member and engaging looselv in a crank arm said cranlc arm hul and crank by a set screw it and will operate through the pin or connections Til to turn the cam member on the tubular bea ring 52. when the parts are re lated as shown in Fig. 8. the cam 45.) will act on the roller porting frame on its pivot and vary auto and change the widthwise portion ot' the rib bon that is presented to the types. Daring swinging movements of the lever frame and 3 swing up and l alien-ting the the vibrator. the linl; 513 will down on the pivot 35 without bell crank which arries said pivot.

be apparent that simultaneously with the bodily movement of the vibrator the ribbon will be fed lengthwise from one speol to the 2 other so that in effect a siinhltzineous lengthwise and (:1OS .\\iSO feed of the ribbon will be obtained. the path followed by the types being wavy or serpentine. as indicated by the dotted line 1 in Fig. 10. a fragn'u-nt of a ribbon JR which is uniform in character throughout. having only a sin gle color field which extends the full width of the ribbon.

When ribbon vibrator and the supporting arms 26 would drop down under the influence of gravity it additional means were not. pro- .ided for controlling their position. Such additional means in the present instance are Ordinarily when use is having fields ot' ditferent 5 controlled by a liQ V and are operated by said key to set and maintain the vib ator and, 1ts supporting member in predetermined positions. The means just referred to comprises a hand controlled abutment; or supporting pin 69 (Figs. 1. 2 and 3). which underlies the lefthand one of the pair of arms 26 and extends laterally from a crank arm 70. said crank arm having a hub 71 which is secured by a set screw 72 to the inner or right-hand end of a rock shaft 73. Said rock shaft bears in lugs 74 depending from the under side of the top-plate and is adapted to be turned or rocked by devices which include a crank arm 75 secured-to the rock shaft outside the left-hand lug 74 by a set screw 76 which passes through the hub'77 of said crank arm. The crank arms 75 and T0 provide in effect a bell crank with an elongated pivot 73, the arm 7 0 extending upward from the pivot 73 while the arm 75 extends rear ward therefrom and is connected by a de Said lever pending l'ink 78 with a lever 79. lies at the left, of the bank of printing kcy levers. bein; pivoted at 8 in the rear of the base and provided with a suitable restoring spring 9. The lever T5) terminates at its forward end in an u 'nvardly extending por tion T9 near the top of which at 80 is piv oted a short key stem 81. The key stem 81 terminates at its top in a finger key or button H2 and at its lower end in a rearward hook 83. The pivotal movement of the key stem 81 on the key lever limited by a pin and slot connection S4. 85. leaf spring 86 secured to the lower end of the key stem cooperates with a lateral pin 87 on the lever extension 79 to n'iaintain the key stein normally sub- I stantially uprigl'lt on said extension 79, as shown in Fig. 3. \Vhen the lever 73) has been depressed by pressing on the key 82 it may be locked in (lQlJl'tSrQtl position as shown in Fig. l by swinging the key stem 81 on its pivot 80. causing the hook 8:) to engage with a cooperating dctent. Said detent is in the form of a bent plate 88 (Figs. 1 and 6). said plate having slots SH which receive screws 90 which adjustably secure the plate to the front of the usual comb plate or reed bar U]. or to any other suitable support. \Vhc'n the lever 79 is locked in. the depressed or Fig. l position. it will operate through the described ('t'lll|t* tlt ll including the link 78 and bell crank Tl).

The MIIJPHI'tillQ' pin will act on the left hand arm it; to maintain the sum'iorting or lever member and the pivotal center 25 statioimrv so that when the key levers are operated the vibrator will be swung to and fro around a lixcd center and will present the lower lield w of the ribbon ll types. causing said types to follow a straight path lemgthwise of the licld c. as indicated bv the dotted line /1 in Fig.1]. \t'ht-n it i llt'. .ll'(! l to mak use of the upper ribbon licld b of the ribbon .1 the lever 79 may be re leased by pressing rearward on the finger to the 1 key 82. permitting the spring 9 to restore the parts to the position shown in Fig. 3. It will be apparent that during the movement of the parts from the Fig. 1 to the Fig. 3 pcsition. the supporting pin, device or abutment to will swin; for ard and downward, 'iermitting the arms 26 of the pivoted lever to swing down around the pivotal center 27, {thus lowering the pivotal center 25 and l'flYtllly moving the vibrator downward so that when next vibrated by a printing key it will bring the ribbon field b opposite the printing point on the platen. As long as the parts are maintained in the Fig. 3 position the ribbon field 7) will be used and the types will follow a path longitudinal of said field as indicated by the dotted line j in Fig. 1.1..

In order to limit: the setting movements of the vibrator under the control of the key lever T9 so as to write along the ribbon fields and of the two-color ribbon t1, adjustable stop means for the mechanism Controlled by the lever T9 are provided. Said slop means are :-hownin Figs. 1, 2'and 4 and comprise ar arm 92 secured by a'set screw 93 to he lefthand end of the rock shaft 73 outside the, machine frame. Said arm adapted to t-ot'iperate with adjustable screw stops 5H and )3. each screw stop being provided with a locking nut 96. The screws 94 and 93 are supported in the downwardly converging arms 97 of a bracket- 98. said la'acket being secured by screws 99 to the under ide of the top plate 3. The engage mcnt of the arm 92 with the screw stop 95, l as shown in Figs. 1 and -l. limits the upward movement of the pivotal center 25. while when the rock shaft 73 is swung oppositely the arm )2 will contact with the screw stop 94 to limit the downward movement of the pivotal center 25. The screw stops 94 and 95 are so adjusted that they substantially correspond with the limits of movement of the pivotal center 25 as determined when it is automatically controlled by the throw griwn by the cam it). The result is that the width of the serpentine path I followed by the ribbon when it is automatically shifted idthwise. ctirresptaids with the distance between the parallel paths (1 and 0 followed by the types when the ribbon is shifted 'widthwise and set by hand.

\Vhilc. of course. a uniform ribbon may be shifted widthwise by hand by actuating the linger key 82 and the devices controlled thereby. and a two-color ribbon may be anttnnaiically controlled by the cam 49, it is usually desirable. as has been stated. to employ the cam with a uniform ribbon and the hand control with a two-color ribbon so that when a two-color ribbon like 38 is on the machine the automatic devices comprising the am l9 will be employed ordinarily t0 the exclusion of the hand operated devices 1 controlled by the key 82. Then, when the uniform ribbon of the dual characteristics like 11 is sub stituted in its thrown out and the hand operated devices made use of with such a ribbon 11.

It will be observed that by my present inanism for automatically controlling the viis removed and the ribbon l tion of a place, the cam 49 Will be platen, a vibratory ribbon carrier, support with which said carrier connected, means for swinging at printing operation independsupport toward and away from a pivoted is directly said carrier ently of said I said platen substantially radially thereof, a ventlon I provide simple and eflicient mechbratory ribbon so as to feed it widthwise and for controlling ter so that either one of its fields may be made use of at pleasure.

Various changes may be made without departing from the spirit of my invention.
